, o 4 "2 Claims. My invention relates to improvements in dish washers and pertains particularly to the rotary cage type, adapted to wash and rinse dishes and the like. l l l In `the accompanying drawings:

Figure 1 is a perspective view of a dishfwasher in accordance with my invention illustrating the cover parts of the cabinet in openpositions;

Figure 2 isa vertical sectional view;l

Figure 3 is a top view with the covers removed,

with a portion` of the structure broken away;

Figure 4 is a horizontal sectional view;

Figure 5 is .a bottom view of a container basket; and

Figure 6 is a top view of a multiple device.

In the embodiment of the invention selected for illustration, I make use of a cabinet I0, as in Figure 1, made up offour side walls I2 arranged to provide an enclosure square in cross (section, as when viewed in Figures 3 and 4. The walls I2 are of equal length and support a bottom I4 spaced ashort distance inwardly from the lower ends of the walls. All the walls and the bottom are preferably formed of wood.

Inside the cabinet I0 is arranged a metallic, earthenware or plastic liner I6, as in Figure 2, circular in cross section, to moistureproof the cabinet I0. While the liner I6 has four points of contact with the Walls I2, additional support is aiforded by diagonal wooden strips I8 arranged at forty-live degree angles `to the engaging walls and located at the upper end of the liner. This liner has a flat bottom 2D resting on the bottom I4, with the upper end of the liner terminating substantially nush with the upper ends of the walls I2. An annular flange 22 is carried by the liner I6 a short distance inwardly of its upper end.

Inside the liner I6 is mounted a rotary cage or receptacle 24 for containing dishes and the like to be washed. This cage includes a wall 28 circular in cross section and a bottom 30. Both the side wall and the bottom are formed of wire mesh, with the mesh of the bottom slightly larger than in the wall to facilitate passage of solids washed from the dishes.

'I'he bottom 30 of the cage rests on a supporting structure 32 extending-upwardly inside the cage and connected with a top supporting structure 34. The supporting structure 32 comprises two especially treated wood bars 36 crossed in right angular relationship and intertted at 38 so as to lie in a common plane. Four upright bars 40 are secured to the outer ends of the bars 36. Recesses 42 are formed in the upper faces of the arms 36 for receivingthe lower ends of the bars 40. Slots are cut in the bottom 30 to accommodate the bars 48. Two of the bars 40 are arranged edgewise to the wall 28 in a common plane and the remaining bars are arranged fiatwise against the wall.

The upper supporting structure 34also comprisesV right angularly crossed arms 44 interitted at 46 to lie in a common plane and recessed at 48 to receive the upper, ends `of three of the bars 40. The outer ends of the bars 44 t inside the wall 28, as in Figure 3.

Upon the wall 20 is mounted a body 50 provided with a recess 52 for receiving a convexed bearing 54 conforming to the shape of the recess. This bearing is provided with 'a flange 56, as in Figure 5, secured to the bars 36 by screws 58.

A short shaft 62 is provided with arms 64 xedly secured to one of the bars 44 by screws 66. An opening 68 is provided in the bars 44 through which the shaft 62 is extended for pivotal connection at 'IIJ with a crank 'I2 through the medium of which the cage is rotated relatively to the cabinet. This crank is provided with a knob I4 to facilitate manual rotation of the cage. To the two bars 40 lying facewise against the wall 28 are attached two agitators I6 arranged at an angle of about forty-ve degrees to their respective bars 40. Both agitators 'I6 comprise especially treated wood or plastic members having their upper and lower ends tting in recesses in the top and bottom supports 34 and 32, respectively.

A water inlet pipe 'I8 extends through one wall of the cabinet I0 and has communication with the liner I6. This pipe is located a short distance beneath the upper end of the liner and slightly above an overflow pipe 88 communicating with the liner and extending downwardly between the liner and the cabinet I0 in one corner thereof, through the bottom I4 for connection with a T 82 coupled to an outlet pipe 83. The T 82 extends through the bottoms I4 and 20 and is normally closed by a convexed body 84 attached to a carrier 86 hingedly connected at 88 with b ottom 20.

To the carrier 86 is connected one end of a rod 90 extending upwardly inside the liner I6, through an opening in the annular flange 22 and through slots 92 in cover sections 94 hngedly connected at 96 with the upper ends of two of the walls I2.

To the inner face of each cover section 94 is attached a rib 98, as in Figure 1, the two ribs providing an annular ribwhen the cover sections are closed to bear on the annular ilange 22 and provide a watertight seal. A slot |00 is formed in each cover section to provide accommodation for the crank 12. The cover sections are also provided with flanges |02 having overlapping engagement in the closed positions of the cover sections.

One of the bars 44 extends only from the other cross bar 44 to the peripheral wall of the cage 24, as in Figures l and 3. 'This provides a large opening intheiupper end-A of thelfcagefto facilitate loading and'removal offv the articles.. The greater part of the washer is fornied of especially treated wood or plastic so as to require a relatively small amount of metal.

In operation, the liner I6 is filled with water up to the inlet of the overflow pipe 8,0:l Rotation of the cage imparts an eilicient washing agitation to the liquid by reason of the arrangementfoff the two agitators 'I6 and the two bars;` 40 ar.- ranged edgewise to the cage.
